It is a collection of 4k textures for use if you have meshes that have parallax enabled... IE parallax remastered etc.

It also does contain some meshes for things that other mods have not touched.

The description etc is really confusing and lacking, but long story short.

If you download EVERYTHING then there is no double up on anything. Everything he makes he seems to put into a new folder and then upload.

He does cover a rather large selection of textures by now, and they are super 4k quality without exception.

Essentially this is for screenarchers only.. it is not really meant for playing. I use a few of his textures here and there, since some of them are vastly superior to what else is around... I do tend to downscale them to 2k though.
